## **MUN12AD05-SMF SERIES** 

## ~~ee~~ **APPLICATIONS INFORMATION: (Cont.) INPUT FILTERING:** 

The module should be connected to a source supply of low AC impedance and high inductance in which line inductance can affect the module stability. An input capacitor must be placed as near as possible to the input pin of the module so to minimize input ripple voltage and ensure module stability. 

## **OUTPUT FILTERING:** 

To reduce output ripple and improve the dynamic response as the step load changes, an additional capacitor at the output must be connected. Low ESR polymer and ceramic capacitors are recommended to improve the output ripple and dynamic response of the module. 

## **LOAD TRANSIENT CONSIDERATIONS:** 

The MUN12AD05-SMF module adopts the instant PWM architecture to achieve good stability and fast transient responses. In applications with high step load current, adding 47pF Capacitor (CFB) in parallel with RFB1 may further speed up the load transient responses. 

## **PROGRAMMING OUTPUT VOLTAGE:** 

The module has an internal 0.6V reference voltage. The output voltage can be programmed by the dividing resistor (RFB1 and RFB2). The output voltage can be calculated by Equation 1, resistor choice may be referred TABLE 1.

## **RECOMMENDATION LAYOUT GUIDE:** 

In order to achieve stable, low losses, less noise or spike, and good thermal performance some layout considerations are necessary. The recommendation layout is shown as Figure 40. 

1. The ground connection between pin 1, 7, 8, 21 and PIN12 to15 should be a solid ground plane under the module. It can be connected one or more ground plane by using several Vias. 

2. Place high frequency ceramic capacitors between pin 9 to 11 (VIN), and pin 7 to 8, pin 21 (PGND) for input side; and pin 2 to 5 (VOUT), and pin 7 to 8, pin21 (PGND) for output side, as close to module as possible to minimize high frequency noise. 

3. Keep the RFB1 and RFB2 connection trace to the module pin 18 (FB) short. 

4. Use large copper area for power path (VIN, VOUT, and GND) to minimize the conduction loss and enhance heat transferring. Also, use multiple Vias to connect power planes in different layer. 

5. If the system chip interfacing with the pin 20 (EN) has a high impedance state at shutdown mode and the VIN pin is connected directly to a power source such as a Li-Ion battery. A 1MΩ pull down resistor should be placed between the enable pin and GND pins to prevent the noise from falsely 

turning on the regulator at shutdown mode.

## **REFLOW PARAMETERS:** 

Lead-free soldering process is a standard of electronic products production. Solder alloys like Sn/Ag, Sn/Ag/Cu and Sn/Ag/Bi are used extensively to replace the traditional Sn/Pb alloy. Sn/Ag/Cu alloy (SAC) is recommended for this power module process. In the SAC alloy series, SAC305 is a very popular solder alloy containing 3% Ag and 0.5% Cu and easy to obtain. Figure 56 shows an example of the reflow profile diagram. Typically, the profile has three stages. During the initial stage from room temperature to 150°C, the ramp rate of temperature should not be more than 3°C/sec. The soak zone then occurs from 150°C to 200°C and should last for 60 to 120 seconds. Finally, keep at over 217°C for 60 seconds limit to melt the solder and make the peak temperature at the range from 240°C to 250°C. It is noted that the time of peak temperature should depend on the mass of the PCB board. The reflow profile is usually supported by the solder vendor and one should adopt it for optimization according to various solder type and various manufacturers’ formulae.
